Application filed November 26, 1920. Serial No. 426,489.

To all whom it may concern.

Be it known that l, CHARLES E. CONNER, a citizen of the United States, residing at Auburn, in the county of Androscoggin and State of Maine, have invented certain Improvements in Attaching Machines, of which the following description, in connec tion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

My invention relates to attaching machines, especially involving the jacks or work-supports found in such apparatus as that employed for nailing or tacking counters t the soles of turn shoes prior to their turning. There is a machine of thi character which is a modification of the wellknown Lightning heeler, and is describedin an aiplication filed in the name of Joseph H. lope on October 4, 1920, Serial No. 414,501. To support the counter in position for nailing, the die-block of the machine is provided upon its under side with counter-supporting block, against which the heel-seat of the shoe operated upon is pressed during the nailing of the counten In attaching high counters, the travel of the cross-head carrying the jack may not be sufficient to remove the upper edge of the counter below the supporting block, and this interferes with the drawing out of the jack to remove the work.

An object of this invention isto provide a machine which operates in this manner upon the work, but without interference between the attached element and its support, and without requiring the operator to perform special acts to attain the desired re sult. To this end, I combine with a worksupport, or jack, and mechanism for operating upon the work, as nailing instrumentalities, means for temporarily retaining the work-support in position for the operation,

together with means for actuating the retaining means to releasethe work-support, and means controlled in the operat1on of the machine and independently of movement of the work-support for restoring said worksupport to operating position. This auto matic control under the power of the machine may be in the nature of a preparation of. the restoring means for operation, as by effecting the compression oi. a spring, which thereafter causes the work-support to be returned to the operating position. To allow the restoration to take place at the desired time, there is associated with the restoring means, a means for holding it as thus prepared. The holding meansyas illustrated, consists of a latch cooperating with the spring, and it may be caused to act as a result of movement of the work-support. By making this incident to another operation, the operator is not only relieved of the effort of preparing the restoring means for action in the manner already pointed out, but also of the initiation of the restoring action. The retaining means for the works support, which limits its movement or holds it for the attaching operation, is shown as movable to allow the support to be "freed to retreat from the attaching mechanism, and this movement is preferably controlled in the operation ofthe machine. The use of this organization in a counter-attaching machine results in the jacked work with the attached counter being held against move-. ment for the attaching operation, released and moved away from the attaching mechanism so that it may be shifted without'contact between the counter and its support, and finally the jack restored to and retained in the attaching position, all. withouteifort on the part of the operator other than what has been heretofore required in connection with the ordinary operation of machines of the previously mentioned Lightning heelerp Of this it will be suiiicienttosay that it has a frame 10, carrying above the usual actu- .ating mechanisms a die-block 12, with the nail-receiving openings of which co-oper ate drivers 14. These drivers are fixed to a' top girt15 carried by reciprocatory side rods 16' and 18. A jack J, arranged to receive a last L, upon which is to be supportthe attached counter.

of the last L.

ed a shoe which is to have attached to it a counter C, is mounted upon the customary reciprocatory crosshead 20. Beneath and having openings in alinement with the dieblock openings is secured a counter-supmounted to slide in horizontal ways 28 in thecross-head from the front toward the rear of the machine This lateral movement carries the jacked work into the attaching position beneath the support 2:2, or outwardly therefrom free from the die blojckto enable the operator to apply to the jackthe lasted work, or to remove this with At the rear of the base, rising vertically from it, is a tubular standard 80, in which is arranged to move a jack-post 32 having at its upper extremity a spindle 34 to enter the opening; in the cone Situated beneath the toe of the last, I have shown a toe-rest 36, which may be of any suitable form, supported upon an arm 38 extending from the jackpost and being adjustable vertically and horizontally tobring it into correct relation withthe toe of the lasted shoe supported upon the jack. The jack-post is threaded at 40, and on this threaded portion is a con tact member, provided by anut 4L2. lVith the under side ofthis nut may Contact a ret aining member, consisting of a slide ea,

carried for horizontal'movement at the top of a lateral extension 43 of the base 2'5. Upon the lower'side of the slide is formed or secured'a rack d6; having meshing with it a'pinion 4L8, the spindle of which is journaled in the extension 4.3. WVith this pinion also meshes a gear-segmentfiO, journaled upon the standard extension and having projecting from it in a. substantially hori- Zontal direction an arm 52. Between this arm and the jack base extends a helical tension-spring 54, which acts through the gearing" connections to urge the slide 44 normally toward the j a'ck-post. Fixed upon the side rod 16, adjacent to the jack, is a bracket 56, having pivoted at the inner side of the rod a contact member '58, which is held by a spring toward the jack and with its end in vertical alinement with the extremity of the arm 52. When, in the operation of the machine,the side rod descends, the member 58 moves idly by the'arm, yielding outwandly to avoid interference. On the return or'upward movement, however, the contact member, strikingthe arm, rotates the gearsegment in a clockwise direction, this movem'ent being transmitted through the pinion to the slide, carrying this away from the jaokpost so that it is removed from beneath the nut 42. The jack thus freed may fall by gravity until the nut contacts with the top of the standard 30.

interposed between the jack-post and the standard is a sleeve 62, lit-ting said standard for reciprocation within it, and in which the jack-post has a sliding fit. Between the oase'and the sleeve is situated such a motor means as a helical compression spring 64, of such length and strength that it will raise the ack and work until the nut 42 is above the top of the slide 44 The upward movement the sleeve within the standard may be limited by the reduced end of a screw 66 threaded through the wall of the standard into a vertical slot of suitable length in the sleeve. A similar screw 68, threadec through the sleeve,'may project into a slot in the jack-post to prevent its rotation. From one side of the sleeve 62 is a projection 70, passing through a vertical slot in the standard and lying in the path of a contact arm secured upon the side rod 18 oi the machine. ri lion the top-girt is.low ered in its dri""ngg stroke, the member 72, striking theprojection 70, depresses the sleeve '62 and compresses the spring 64. In

this lowered position, the sleeve is held against the expansive force of the spring by a latch 74, ")ivoted at '76 upon the jack base and-having an engaging end entering a depression 78 in the sleeve. The latch is forced normally toward the sleeve by a spring 80 interposed between it and the base, and the latch may be withdrawn from the sleeve opening to release. the sleeve by con-- tact of its lower extremity with a bar 82 fixed upon or forming a part of the frame at the front oi the cross-head :20. This contact and the disengagement of the sleeve by the latch occur when the jack is drawn out for the purpose of removing; from it the shoe with its attached counter. i

in using; a counter-attaching machine arranged in accordance with the present in ention. the operatorapplies to the block the counter (l which to be attached, and, the jack base being; drawn forward. places the lasted shoe upon the pin 34 of the jack. the applied countenit will be assumed for the purposes of the present description, is'ot a greater hein'ht'when attached to the shoe than the downward ravel oi the cross-head. That is, when the cross-head is lowered after the attachment of the counter. the upper edge of said couuterwill still project abo e the bottom of the block .T'he jac; is then pushed in until the rear of the shoe contacts with the 247-. The work thus positioned, the operator StflFt'S. tl1(-3 machine, the cross-head risingg' to clamp theheel-seat oi the shoe against the counter upon its block, and the drivers descending force through the counter into the heel-seat of the shoe the Jun is again pushed in beneath the block nails or tacks which have previously been supplied by the usual loading mechanism to the openings in the die-block. During this movement of the drivers. involving, the descent of the side rods, the contact member 72 strikes the projection 70, lowering the sleeve 6:2, which is locked by the latch 74, the spring (34: being held compressed. The jack remains supported by the contact of the nut 4L2 with the slide 44:, which at this time is held at its inward position by the spring 5%. driving; operation, the contact member 58, after having traveled downwardly past the arm 52 without action. raises the arm and through the associated gearing; moves the slide 44.- away from the jack-post. This carries it from beneath the nut 42. and the jack, being thus freed, falls by gravity to its lowest position, at which time the nut 41-2 is in proximity to the top of the standard 30. The upper extremity of the now depressed and locked sleeve 62 is also, it should be noted, at or below the top of the standard, so that it does not interfere with the descent of the jack. This fall of the jack lowers it and the shoe snfiiciently to carrythe upper edge of the attached counter. below the l)0tt011'l0ii the block 22, so that said counter is free to move past the block. The jack is then drawn out, and the lasted shoe is taken from the post. At the end of the forward travel of the jack, the tail of the latch 74; comes in contact with the bar 82, drawing the engaging end of the latch out of the opening 78. The sleeve 62 is thereby freed, and the spring G lexpanding, raises the sleeve, which, by its contact with the nut4t2, also elevates the jack. This action continues, the side oithe nut moving along; the inner face of the slide until the lower face of the nut is above the upper edge of said slide, when the spring 54;, acting through the arm 52 and. associated gearing, carries the slide beneath the nut. The. elements of the jaclr are now restored to their initial condition, and. are ready to receive another lasted shoe. This having been applied. the jack and. with the application of a counter to this block, the machine is ready for the sho (coding operation.
